They say you can't go home again, but that won't stop some people from trying. In "The World's End," Simon Pegg plays a dodgy fellow named Gary who's determined to get his stodgy grown-up friends to recreate a pub crawl they went on 20 years ago. Their destination? A pub called, you guessed it, The World's End. They didn't make it there last time -- 12 pubs is rather a lot -- but this time, darn it, they'll see it through no matter what.

As Gary, Pegg drags his frequent co-star Nick Frost, actor/director Paddy Considine, Martin Freeman of "The Hobbit" and "Sherlock" fame, and serious dramatic actor Eddie Marsan along for the ride. Sure enough, The World's End and their goal of total drunken annihilation becomes a fight to save the world from glowy-eyed aliens. Of course, it's all a clever metaphor for growing up and all that, but still, braindead suburbanites! Beer! Boyish shenanigans!

Pegg and director Edgar Wright wrote "The World's End." Along with Frost, they're famous for collaborations on "Hot Fuzz," "Shaun of the Dead," and British TV show "Spaced," so you know "The World's End" will be loaded with pop culture references and rapid-fire humor. The trailer is so tantalizing, from Pegg's grungy aging teen look to Freeman's dorky Bluetooth earpiece. As Pegg told USA Today, "When Edgar and I were pitching it to each other, we had this idea as it being like 'The Big Chill' but if the corpse came along for the ride. That's Gary."

Sadly, "The World's End" is a sort of bookend to "Shaun" and "Hot Fuzz," meaning that, although it's likely the trio will work together again, this will be the end of their "blood and ice-cream trilogy." As Pegg described it, "'Shaun of the Dead' has strawberry, 'Hot Fuzz' has the original Cornetto flavour, and there will be a mint-choc chip in the third film."
